Some of these storms produced tornadoes, large hail, and damaging winds (SPC storm reports<\/strong><\/a>) in addition to heavy rainfall, with as much as 9.00 inches in Minnesota and 9.80 inches in Wisconsin (NWS Duluth storm summary<\/strong><\/a>). Several highways were closed due to flooding and\/or washout, including a portion of Interstate 35 in Minnesota (interstates and highways are plotted in violet on the images).<\/p>\n

A sequence of Infrared images from Terra\/Aqua MODIS (11.0 \u00b5m) and Suomi NPP VIIRS (11.45 \u00b5m) (below)<\/strong><\/em> showed greater detail in the storm-top temperature structure at various times during the event.<\/p>\n
